Suppose that a 1.00 cm3 box in the shape of a cube is perfectly evacuated, except for a single particle of mass 1.23 10-3 g. The particle is initially moving perpendicular to one of the walls of the box at a speed of 460 m/s. Assume that the collisions of the particle with the walls are elastic.
(a) Find the mass density inside the box.
(b) Find the average pressure on the walls perpendicular to the particle's path.
(c) Find the average pressure on the other walls.
(d) Find the temperature inside the box.

On a hot summer day in the state of Washington while kayaking, I saw several swimmers jump from a railroad bridge into the Snohomish River below. The swimmers stepped off the bridge, and I estimated that they hit the water 1 s later.
Assume that the blocks accelerate as shown with an acceleration of magnitude a= 0.550 m/s^2 and that the coefficient of kinetic friction between block 2 and the plane is μ= 0.400. Find out the mass of block 2, m2, when θ= 30.0.
